FreeBSD mobileKamikaze.norad 8.0-STABLE FreeBSD 8.0-STABLE #1: Tue Feb 23 10:37:52 CET 2010     root at mobileKamikaze.norad:/usr/obj/HP6510b-8/amd64/usr/src/sys/HP6510b-8  amd64
>Description:
It appears that the PHP5 module /usr/local/lib/php/20060613/gd.so, at least on amd64, does not manage to load libpng.so.5, even though ldd is able to locate it.

This causes attempts to load PNG images to fail:
Warning: imagecreatefrompng() [function.imagecreatefrompng]: gd-png: fatal libpng error: [00][00][00][00]: unknown critical chunk in /usr/home/kamikaze/devel/workspace/realmsofsorrow/nightmare/core/nmTemplate.class.php on line 385
Warning: imagecreatefrompng() [function.imagecreatefrompng]: gd-png error: setjmp returns error condition in /usr/home/kamikaze/devel/workspace/realmsofsorrow/nightmare/core/nmTemplate.class.php on line 385
Warning: imagecreatefrompng() [function.imagecreatefrompng]: './templates/neo/layout/header_stretch.png' is not a valid PNG file in /usr/home/kamikaze/devel/workspace/realmsofsorrow/nightmare/core/nmTemplate.class.php on line 385

I expect that saving doesn't work as well, I didn't test it, though.

I do not know whether other platforms are affected. But 2 more people emailed me, that they have the same issue. Both mod_php and php are affected.

For more detail look at my post on ports@:

>How-To-Repeat:
Try to use PNG image functions with php5-gd on amd64.
>Fix:
I do not know how to fix this, but I am currently using a very clumsy workaround:

# env LD_PRELOAD=/usr/local/lib/libpng.so.5 /usr/local/etc/rc.d/apache22 restart
